It's men versus women, and each team must devise their own name and select the project manager for the other team. The men - Team Rocksolid - opt for Cyndi , reasoning she might irk the other contestants, while the women - Team Tenacity - choose Bret because he's admitted to being sleep deprived.

Their first task is to run a diner in New York, taking charge of the menus, cooking and serving. The project manager for the team that makes the most money, including tips, will be awarded the money for their charity. One person will be fired from the losing team.

Team Rocksolid - Diner on 53rd and Madison

Bret decides to hand control over to Curtis because he is a professional chef. Curtis suggests they target more affluent customers, with a strategy of high-price points, including $250 for a truffle risotto. Curtis devises the menu based on what is in the fridges, and calls his contacts to get the high-end ingredients.

Sinbad works outside the diner bringing in the customers, while Darryl hosts, Michael is clerk, Rod is the server and Bret is the bus boy. They hit an initial stumbling block when some customers leave without eating because of the high menu prices, but gradually the diner begins to fill up. Curtis calls in a favor from his Today Show friends, and among the stars who turn up is Al Roker. The other team members also call in personal favors, and several customers end up leaving $1,000 plus.

Donald Jr. arrives to see what's happening, and thinks the team is organized and working well together. He adds that Curtis is doing a great job, but that's expected because it's his profession.

Team Tenacity - Diner on 62nd and Lexington

Their strategy is price-for-volume and Cyndi decides everything should be around $20 with one signature dish at $100 for those who want to donate. Everybody calls in their contacts to come down and help the cause, while Sharon and Cyndi organize radio promotion.

Holly acts as accountant, Selita and Summer cook, Carol works the crowd outside, and Maria, Sharon and Cyndi are servers. Sharon also corners a lurking paparazzo and asks him to take photos of them at the diner to increase publicity.

The crowd outside the diner steadily grows, and Holly worries that some of the promised big donors might be left outside. She asks Carol to stop handing out flyers and come in and help in a bid to speed up the turnover of customers.

Donald Jr. thinks there is a "good measure of chaos" in the diner, and points out he's seen several men he knows from Wall St. and charitable trusts so they must be making some big tips.

The Board Room

Donald says he called in a special favor from former winner Joan Rivers. She had visited both diners during their challenge and picked her favorite, who will receive an additional $10,000 on top of what they have made. She chose Team Tenacity, saying that the boys' food was cold because server Rod took too long getting it from the kitchen to the table.

Donald rounds the total income from both to $100,000, which is awarded to diabetic Bret's charity, the American Diabetes Association. The women remain in the boardroom. They explain that many of their contacts were not in New York, while Ivanka questions whether their low price-point was the issue because people came off the street and tied up the tables.

Donald asks them who should be fired, but no-one wants to answer until Maria suggests Carol. Holly thinks it's between Cyndi and Carol, while Sharon says Carol, although Cyndi - and the boys who are watching via TV - think it's a mistake. Carol defends herself by saying they will need her creativity later in the game, but Sharon calls her under the radar.

Cyndi can't decide which two people to bring back into the boardroom, so Donald says he has no choice but to fire Carol because the other members of the team had pointed that way. Before leaving, she manages to secure a $10,000 donation to her charity, the North Shore Animal League.
